ABSTRACT:
A magnetic component (i.e. inductor or transformer) utilizes sheet winding patterns designed to enhance component assembly and maximize utilization of the core window areas. The windings are obtained from a copper sheet from which sheet winding patterns are obtained by etching, stamping or cutting the copper sheet. These winding patterns are contoured to fit precisely into the window area of the core of the magnetic component so that the window area is fully utilized. Basic symmetrical copper sheet patterns are used and these are sequentially stacked and combined to achieve multiple turn windings. These assembled winding components are connected to a bobbin which includes pins at its periphery to interconnect the copper sheet winding patterns to obtain the desired number of turns of the windings.
The bobbin structure supports the component on a circuit board with the magnetic core of the component protruding through an aperture in the printed circuit board in order to permit a low profile mounting for the component.
